An efficient way to decrease these emissions is the replacement of gasoline PCs (passenger cars) by diesel ones, which emit less CO₂. Most of the member countries of the EU have high percentages of new diesel PC registrations; however, this percentage remains less than 17% in Ireland. The benefit on CO₂ emitted from new PCs is studied in the case of an increased diesel penetration in Ireland, after several scenarios using the current and estimated future PC sales and estimated fuel consumption. The results show that, in the case of new PCs, a CO₂ benefit of more than 2.9% can be achieved, if a diesel penetration higher than 30% occurs in the case of the current fleet. If this penetration reaches 50%, this benefit will be higher than 7.4%. Future total CO₂ emissions from new PCs can be partially controlled by the introduction of diesel PC or the replacement of heavy PCs by lighter ones. Future fuel consumption of gasoline and diesel PCs and the percentage of diesel penetration are the key factors for this control. (8 figures, 2 tables, 18 references)
